I put in water catch barrels on each of my structures:
1. The run off on dry hard soils will create erosion
2. Using them to irrigate using a drip system helps with absorption as it is slower
3. This also helps grow longer root systems and the water will over time help the overall health of the area instead of runnin off which is a problem in the high desert which evident in the arroyos
Next spring, I am going to continue, like Kevin to build catch ponds in any area where there is already some erosion happening. Bill Zeedyk has a couple of great books on high mountain wetland restoration that may help.
Joe mentioned that Kevin has started a seed bank, I am interested 👽
